About

Fei is an AI-powered engineering agent that operates directly within your codebase, intelligently reusing components and adhering to your design system and coding standards to generate production-ready backend code that often passes review on the first try. It ingests inputs such as Figma designs, Jira tickets, screenshots, or plain text and transforms them into backend-ready code within minutes, significantly accelerating development cycles without compromising quality or security. Fei acts as an autonomous teammate rather than just a coding assistant, enabling scalable output without adding headcount and ensuring that generated code aligns with existing infrastructure and conventions. This level of integration and contextual awareness means teams can ship real products, not prototypes, with confidence, speed, and consistency.

About

Knapsack is a digital production platform that connects design and code into a real-time system of record, enabling enterprise teams to build, govern, and deliver digital products at scale. It offers dynamic documentation that automatically updates when code changes occur, ensuring that documentation remains current and reducing maintenance overhead. Knapsack's design tokens and theming capabilities allow for the connection of brand decisions to style implementation in product UIs, ensuring a cohesive brand experience across portfolios. Knapsack's component and pattern management provides a birds-eye view of components across design, code, and documentation, ensuring consistency and alignment as systems scale. Its prototyping and composition features enable teams to use production-ready components to prototype and share UIs, allowing for exploration, validation, and testing with code that ships. Knapsack also offers permissions and controls to meet the complex workflow.
